  • Patent number: 5853817
    Abstract: The present invention provides a method for producing a a high-performance black matrix taking the palce of a Cr film black matrix and a high-performance color display thin film, which is comprises steps of vaporizing one or more organic pigments or vaporizing and exciting a metal or an alloy together with said organic pigments, and forming a thin film or a mixed composite thin film onto a substrate by the plasma exciting deposition.

  • Patent number: 5652030
    Abstract: The substrate (10) is placed in an enclosure (12) and is heated so as to establish therein a temperature gradient such that the substrate has a higher temperature in portions that are remote from its exposed surfaces than at its exposed surfaces. A reaction gas constituting a precursor for the material to be infiltrated is admitted into the enclosure, with formation of the material being enhanced in those portions of the substrate that are at higher temperature. At the beginning of the infiltration process, and at least during the major portion thereof, substrate heating is controlled in such a manner as to maintain the temperature of its exposed surfaces at a value that is no greater than the minimum temperature for the reaction gas to deposit the material that is to be infiltrated, while portions of the substrate that are remote from its exposed surfaces are at a temperature that is greater than the minimum temperature for deposition.

  • Patent number: 5017402
    Abstract: Adverse interactions during initial interactions between abradable seal components are minimized by applying a coating to the moving seal component. The coating is nonreactive with the abradable material and provides lubricity during initial seal operation.

  • Patent number: 4999217
    Abstract: A process for producing a magnetic recording medium includes coating a nonmagnetic substrate with a magnetic paint and applying a rotating magnetic field for orientation to the raw fabric with magnetic paint in a yet unsolidified state on the substrate, in which a magnetic field is applied to the above raw fabric so that the magnetic lines of force may pass from the back face to the front surface or from the front surface to the back surface of the raw fabric before application of the rotating magnetic field for orientation, thereby effecting preliminary orientation.
